2000 Honda Accord Oil Burning
Did you find answer to your oil consumption problem? I have 2000 honda accord 4cyl, and am in exact same situation as you described. My car is at about 96000 miles now, but the problem started about 2 years ago when I was at about 80000 miles. Dealer told me that it is a possible oil leak or oil burn, but they have not been able to pin point the problem. I have to be extremely careful with the oil level and keep checking every 2 weeks to ensure that it does not drop down too low. I do not see any oil spots where I park my car, so it seems to be an oil burn issue. I am showing it to another mechanic tomorrow, but I do not want to be going in circles with no solutions after spending lots of money. Have you found solution to this problem?
Thanks.
A problem with the crankcase ventilation system will caused that as mentioned by Ken-back in the old days when you find an airfilter saturated with oil-the system is blowing backwards. This is what the PCV valve could do when you got pressure in the crankcase, that pressure will find an exit-that blue smoke has oil vapor and can give us the winding curve ball is to where that oil is going to-w/o a leak.
Suggested Repair
Check the PCV valve and crankcase ventilation system, then confirm the oil path with a cylinder leakage test. Compression results point to worn piston rings or valve seals/seats; if confirmed and the car is still under powertrain warranty, pursue an engine repair or replacement with the dealer.
Conversation Summary
A 2000 Honda Accord with about 91,000 miles was burning roughly four quarts of oil every few weeks, losing power, and setting P1259. A shop found a small timing-cover leak, normal coolant, oil at the tailpipe, and uneven compression, and suspected piston rings or valve seals. Experts agreed those are likely causes, advised demanding warranty coverage if still eligible, and also recommended checking a stuck-open PCV valve and doing a cylinder leakage test to pinpoint rings versus valves.
